For outdoor digital billboards, since they are used outdoors, they must be treated differently from ordinary indoor LED displays. LED electronic display installation requirements are also different from ordinary indoor LEDs. Installation must be done in detail. Otherwise it is very likely to cause trouble. Now let's follow the LED display manufacturer Helilai to learn about the requirements for outdoor digital billboards
Six Major Requirements for Outdoor LED Display Installation:
1. Lightning protection device installed on display screen and building
The main body and the outer casing of the LED display are well grounded. The grounding resistance is less than 3 ohms, so that the large current caused by lightning can be discharged in time; the display may be subject to strong electric and magnetic attacks caused by lightning.
2. Waterproof measures for LED display itself
The screen body and the joint of the screen body and the building must be strictly waterproof and leakproof; the screen body should have good drainage measures, and the water can be discharged smoothly once the water accumulation occurs;Pay attention to waterproof and moisture. The display screen is installed outdoors, often exposed to the sun, rain, wind blow, dust cover, and bad working environment. If the electronic equipment is wet or severely damp, it may cause a short circuit or even a fire, causing malfunction and loss.
3. Circuit chip selection
Industrial-grade integrated circuit chips with an operating temperature between -40°C and 80°C are selected to prevent the display from stopping due to low temperature in winter.
4. Install the ventilation device to cool down, so that the internal temperature of the screen will be kept between -10°C and 40°C.
An axial flow fan is installed above the back of the screen body to discharge heat. When the LED display is working, it must generate a certain amount of heat. If the ambient temperature is too high and the heat dissipation is poor, the integrated circuit may not work properly or even be burned, so that the display system cannot work normally.
5. Must use ultra-high brightness LED
In order to ensure long-distance visibility under strong ambient light conditions, ultra-high brightness LEDs must be used; the contrast must be increase; the audience must be widen The audience is wide, the line of sight is far and the vision is wide; Wide line of sight and wide field of view are required. The ambient light varies greatly, especially from direct sunlight.
